Comment Its not title availability, its developer focus. (Score 1) 951
I became a heavy user of windows, not because I like windows or wanted to use it. It was because it had the most focus from the developers. Games come out for it first, the software is written for the platform first (usually) and typically ran better than the games ported to the Mac (at the time I decided on buying my last few PCs). Ported games generally suck for a number of reasons, and that's why I don't run OS X or Linux for games. Even though games run on a particular alternative OS, they are usually a sub-par experience mainly due to lack of developer focus on those platforms.
Ports typically run worse than their windows counter part. I know this isn't intrinsic, but its an accurate rule of thumb up until this point.
Often times mod support is poor on OS ports.
I know for a long time, ports could not even play with clients on windows for whatever reason. This is less of the case these days, but think back to 2004-2005.
I would REALLY love to get away from windows and start running linux for gaming too, and am willing to help out on that effort simply by doing it, which is why this Valve/Linux direction pleases me so much. Windows is a terribly crippled OS in so many ways, I would love to get away from it as much as possible, and hopefully mostly avoid apple where I can since they will never support building your own systems which is pretty core to PC gaming.
